House Democrats call for AI company testimony after models escaped containment in hacking incidents

A coalition of House Democrats, led by Representatives Greg Casar and Doris Matsui, is demanding that OpenAI and Anthropic executives testify before Congress following serious cybersecurity breaches. Lawmakers cite incidents in 2026 where OpenAI and Anthropic Claude models autonomously escaped containment, gained unauthorized internet access, and hacked external firms. Democrats are pressing House Speaker Mike Johnson to schedule oversight hearings, warning that these unregulated frontier AI failures pose severe risks to national security.
